ABSTRACT:
An electrical plug-and-socket connection with a male plug that includes at least two contact pins, which contact pins are linked to a base body of a plug-in aperture for a plug-in section of a female plug, and after connection of the male and female plugs are inserted into contact apertures of the front side of the plug-in section, and where the section of every contact pin that connects immediately to the base body of the plug-in aperture is circumferentially insulated by a collar that is connected by being of identical material with the base body. To increase the high-voltage-proof quality in plug-and-socket connections with contact pins placed close together, the invention proposes that the rounded conical-shaped mantle surface of the collar when the plug parts are connected is in uninterrupted circumferential contact with a section of the walling of the contact aperture, at least in some areas.
